Qx7 not binding

Hi so I have a tinyhawk freestyle and my qx7 broke so I got a new one and it just won’t bind to the drone and beta flight is saying RX loss which mean there is a connection problem could I have some help please you can reply to this or contact me email bensongeorge2004@icloud.com

firmware issue, the new one must have different firmware to your old one.

Thanks for replying so what should I do I only got them three days apart ? Should I upgrade the firmware on it then?
